    現(xiàn)在完成時(shí)是英文時(shí)態(tài)的一種。
    現(xiàn)在完成時(shí)的用法:
    主語+have(has)+過去分詞(done);
    現(xiàn)在完成時(shí)用來表示現(xiàn)在之前已發(fā)生過或完成的動作或狀態(tài),但其結(jié)果卻和現(xiàn)在有聯(lián)系,也就是說,動作或狀態(tài)發(fā)生在過去但它的影響現(xiàn)在還存在。

    擴(kuò)展資料

      現(xiàn)在完成時(shí)可以用來表示發(fā)生在過去某一時(shí)刻的,持續(xù)到現(xiàn)在的情況,常與for,since連用.

      Mary has been ill for three days.

      I have lived here since 1998.

      現(xiàn)在完成時(shí)往往同表示不確定的過去時(shí)間狀語連用,如already, yet, just, before, recently,still, lately等:

      He has already obtained a scholarship.

      I haven't seen much of him recently (lately).

      We have seen that film before.

      Have they found the missing child yet
